What problem does it solve? Building interfaces that match Expo's visual identity requires exact design tokens — colors, typography, spacing, and component styles — which are tedious to reverse-engineer manually. This Skill provides the complete Expo design system so generated UI matches the brand precisely. ## Core Features & Use Cases - Complete Design Tokens: Exact hex colors (Cloud Gray #f0f0f3, Expo Black #000000, Slate Gray #60646c), typography scale (Inter 400–900, JetBrains Mono), spacing, radius, and elevation values. - Component Specifications: Detailed styling rules for buttons, cards, navigation, forms, code blocks, and status badges, including pill-shaped geometry and whisper-soft shadows. - Light & Dark Previews: Bundled HTML preview files (preview.html, preview-dark.html) showing the full token catalog rendered in both themes for visual verification. - Use Case: When asked to build a landing page styled like Expo, the Skill supplies the exact 64px headline with -3px letter-spacing, black pill CTA, and gallery-like 96px+ section spacing that define Expo's look. ## Quick Start Use the design-expo skill to create a hero section styled like Expo's website with a black pill CTA button.
